Thank you, Chair.
It depends on the committee's intent with this motion. If the intent is to invite, then the motion should say clearly that the intent is to invite. If the intent is to summon, the motion should say that the intent is to summon. If it is a summons, then the motion should also include the name of the individual being summoned and a timeline by which they should appear before the committee.
It is also possible for the committee to adopt a motion or debate a motion that invites a witness and then triggers a summons if the invited witness refuses the invitation.
